Source Code

Creating the Document

Nothing special here:
public Document CreateDocument()
{
  // Create a new MigraDoc document
  this.document = new Document();
  this.document.Info.Title = "A sample invoice";
  this.document.Info.Subject = "Demonstrates how to create an invoice.";
  this.document.Info.Author = "Stefan Lange";
 
  DefineStyles();
 
  CreatePage();
 
  FillContent();
 
  return this.document;
}

Defining the Styles

Styles define how the text will look:
void DefineStyles()
{
  // Get the predefined style Normal.
  Style style = this.document.Styles["Normal"];
  // Because all styles are derived from Normal, the next line changes the 
  // font of the whole document. Or, more exactly, it changes the font of
  // all styles and paragraphs that do not redefine the font.
  style.Font.Name = "Verdana";
 
  style = this.document.Styles[StyleNames.Header];
  style.ParagraphFormat.AddTabStop("16cm", TabAlignment.Right);
 
  style = this.document.Styles[StyleNames.Footer];
  style.ParagraphFormat.AddTabStop("8cm", TabAlignment.Center);
 
  // Create a new style called Table based on style Normal
  style = this.document.Styles.AddStyle("Table", "Normal");
  style.Font.Name = "Verdana";
  style.Font.Name = "Times New Roman";
  style.Font.Size = 9;
 
  // Create a new style called Reference based on style Normal
  style = this.document.Styles.AddStyle("Reference", "Normal");
  style.ParagraphFormat.SpaceBefore = "5mm";
  style.ParagraphFormat.SpaceAfter = "5mm";
  style.ParagraphFormat.TabStops.AddTabStop("16cm", TabAlignment.Right);
}

Create Page

Create the page with invoice table, header, footer:
void CreatePage()
{
  // Each MigraDoc document needs at least one section.
  Section section = this.document.AddSection();
 
  // Put a logo in the header
  Image image = section.Headers.Primary.AddImage("../../PowerBooks.png");
  image.Height = "2.5cm";
  image.LockAspectRatio = true;
  image.RelativeVertical = RelativeVertical.Line;
  image.RelativeHorizontal = RelativeHorizontal.Margin;
  image.Top = ShapePosition.Top;
  image.Left = ShapePosition.Right;
  image.WrapFormat.Style = WrapStyle.Through;
 
  // Create footer
  Paragraph paragraph = section.Footers.Primary.AddParagraph();
  paragraph.AddText("PowerBooks Inc · Sample Street 42 · 56789 Cologne · Germany");
  paragraph.Format.Font.Size = 9;
  paragraph.Format.Alignment = ParagraphAlignment.Center;
 
  // Create the text frame for the address
  this.addressFrame = section.AddTextFrame();
  this.addressFrame.Height = "3.0cm";
  this.addressFrame.Width = "7.0cm";
  this.addressFrame.Left = ShapePosition.Left;
  this.addressFrame.RelativeHorizontal = RelativeHorizontal.Margin;
  this.addressFrame.Top = "5.0cm";
  this.addressFrame.RelativeVertical = RelativeVertical.Page;
 
  // Put sender in address frame
  paragraph = this.addressFrame.AddParagraph("PowerBooks Inc · Sample Street 42 · 56789 Cologne");
  paragraph.Format.Font.Name = "Times New Roman";
  paragraph.Format.Font.Size = 7;
  paragraph.Format.SpaceAfter = 3;
 
  // Add the print date field
  paragraph = section.AddParagraph();
  paragraph.Format.SpaceBefore = "8cm";
  paragraph.Style = "Reference";
  paragraph.AddFormattedText("INVOICE", TextFormat.Bold);
  paragraph.AddTab();
  paragraph.AddText("Cologne, ");
  paragraph.AddDateField("dd.MM.yyyy");
 
  // Create the item table
  this.table = section.AddTable();
  this.table.Style = "Table";
  this.table.Borders.Color = TableBorder;
  this.table.Borders.Width = 0.25;
  this.table.Borders.Left.Width = 0.5;
  this.table.Borders.Right.Width = 0.5;
  this.table.Rows.LeftIndent = 0;
 
  // Before you can add a row, you must define the columns
  Column column = this.table.AddColumn("1cm");
  column.Format.Alignment = ParagraphAlignment.Center;
 
  column = this.table.AddColumn("2.5cm");
  column.Format.Alignment = ParagraphAlignment.Right;
 
  column = this.table.AddColumn("3cm");
  column.Format.Alignment = ParagraphAlignment.Right;
 
  column = this.table.AddColumn("3.5cm");
  column.Format.Alignment = ParagraphAlignment.Right;
 
  column = this.table.AddColumn("2cm");
  column.Format.Alignment = ParagraphAlignment.Center;
 
  column = this.table.AddColumn("4cm");
  column.Format.Alignment = ParagraphAlignment.Right;
 
  // Create the header of the table
  Row row = table.AddRow();
  row.HeadingFormat = true;
  row.Format.Alignment = ParagraphAlignment.Center;
  row.Format.Font.Bold = true;
  row.Shading.Color = TableBlue;
  row.Cells[0].AddParagraph("Item");
  row.Cells[0].Format.Font.Bold = false;
  row.Cells[0].Format.Alignment = ParagraphAlignment.Left;
  row.Cells[0].VerticalAlignment = VerticalAlignment.Bottom;
  row.Cells[0].MergeDown = 1;
  row.Cells[1].AddParagraph("Title and Author");
  row.Cells[1].Format.Alignment = ParagraphAlignment.Left;
  row.Cells[1].MergeRight = 3;
  row.Cells[5].AddParagraph("Extended Price");
  row.Cells[5].Format.Alignment = ParagraphAlignment.Left;
  row.Cells[5].VerticalAlignment = VerticalAlignment.Bottom;
  row.Cells[5].MergeDown = 1;
 
  row = table.AddRow();
  row.HeadingFormat = true;
  row.Format.Alignment = ParagraphAlignment.Center;
  row.Format.Font.Bold = true;
  row.Shading.Color = TableBlue;
  row.Cells[1].AddParagraph("Quantity");
  row.Cells[1].Format.Alignment = ParagraphAlignment.Left;
  row.Cells[2].AddParagraph("Unit Price");
  row.Cells[2].Format.Alignment = ParagraphAlignment.Left;
  row.Cells[3].AddParagraph("Discount (%)");
  row.Cells[3].Format.Alignment = ParagraphAlignment.Left;
  row.Cells[4].AddParagraph("Taxable");
  row.Cells[4].Format.Alignment = ParagraphAlignment.Left;
 
  this.table.SetEdge(0, 0, 6, 2, Edge.Box, BorderStyle.Single, 0.75, Color.Empty);
}

Fill in the Content

This routine adds the dynamic data to the invoice:
void FillContent()
{
  // Fill address in address text frame
  XPathNavigator item = SelectItem("/invoice/to");
  Paragraph paragraph = this.addressFrame.AddParagraph();
  paragraph.AddText(GetValue(item, "name/singleName"));
  paragraph.AddLineBreak();
  paragraph.AddText(GetValue(item, "address/line1"));
  paragraph.AddLineBreak();
  paragraph.AddText(GetValue(item, "address/postalCode") + " " + GetValue(item, "address/city"));
 
  // Iterate the invoice items
  double totalExtendedPrice = 0;
  XPathNodeIterator iter = this.navigator.Select("/invoice/items/*");
  while (iter.MoveNext())
  {
    item = iter.Current;
    double quantity = GetValueAsDouble(item, "quantity");
    double price = GetValueAsDouble(item, "price");
    double discount = GetValueAsDouble(item, "discount");
 
    // Each item fills two rows
    Row row1 = this.table.AddRow();
    Row row2 = this.table.AddRow();

    paragraph.AddFormattedText(GetValue(item, "title"), TextFormat.Bold);
    paragraph.AddFormattedText(" by ", TextFormat.Italic);
    paragraph.AddText(GetValue(item, "author"));
    row2.Cells[1].AddParagraph(GetValue(item, "quantity"));
    row2.Cells[2].AddParagraph(price.ToString("0.00") + " €");
    row2.Cells[3].AddParagraph(discount.ToString("0.0"));
    row2.Cells[4].AddParagraph();
    row2.Cells[5].AddParagraph(price.ToString("0.00"));
    double extendedPrice = quantity * price;
    extendedPrice = extendedPrice * (100 - discount) / 100;
    row1.Cells[5].AddParagraph(extendedPrice.ToString("0.00") + " €");
    row1.Cells[5].VerticalAlignment = VerticalAlignment.Bottom;
    totalExtendedPrice += extendedPrice;
 
    this.table.SetEdge(0, this.table.Rows.Count - 2, 6, 2, Edge.Box, BorderStyle.Single, 0.75);

  row.Cells[0].MergeRight = 4;
  totalExtendedPrice += 0.19 * totalExtendedPrice;
  row.Cells[5].AddParagraph(totalExtendedPrice.ToString("0.00") + " €");
 
  // Set the borders of the specified cell range
  this.table.SetEdge(5, this.table.Rows.Count - 4, 1, 4, Edge.Box, BorderStyle.Single, 0.75);
 
  // Add the notes paragraph
